2. Remove one bead of the tire from the rim by grasping it at a point opposite the valve stem with both hands an, at the same time lifting
and peeling one side of the tire off of the rim. If the bead is on too tight to remove it with your hands, use your tire levers to carefully lift
the bead over the rim of the tire. Be careful not to pinch the tube with the lever. This could cause additional damage to the tube.
3. Remove the inner tube and carefully check the outside and the inside of the tire for the cause of the puncture. Remove all debris from
the tire.
4. If there is a cut or hole in the tire you will need to cover it with something to keep the inner tube from getting damaged once it is
replaced. (a dollar bill, spare patch or piece of inner tube is often sufficient for temporary purposes)
5. Either patch the tube following the directions on your patch kit or replace the tube with a new one.
6. Replace the tire and tube on the rim of the wheel. You may need your tire levers to get the tire over the rim. Be careful not to pinch
the tube.
7. Inflate the tube just enough to seat it in the wheel. Check that the tire is correctly placed on the rim and that the tube is not
protruding.
8. Replace the rear wheel in the bike by following step 1 in reverse. ENSURE THE WHEEL IS PERFECTLY CENTERED. Continue to
inflate to the correct pressure.
9. IMPORTANT: SEE STEP 3 IN BELT TENSION SECTION BELOW TO RESTORE INITIAL BELT TENSION SETTING AFTER
REPAIRING REAR TIRE.
NOTE: Patching a tube is an emergency repair. Please replace the tube.
